Our goal : organizing the exchange of information on thermal spraying at the European level.

ETSA is managed by the Board of Delegates, composed of twelve members elected in a secret vote by the College of Members during the assembly general for four years. They can be re-elected. Members by right: the national representatives of the European countries (one representative per country being active in thermal spraying) are proposed by the national members of the association and accepted by the elected members of the Board of Delegates for four years.

Board of Delegates represents key European universities, research centers and companies involved in thermal spraying, performing research and producing feedstock, equipments and coatings on European and international level. The institutions represented by the delegates gather together hundreds of scientists and engineers dedicated to R&D activities dedicated to base research, applied research, equipment and application development , problem solving in the field of thermal spraying, materials science and engineering...

4th Cold Gas Spray Summer School

4th Cold Gas Spray Summer School

The 4th Cold Gas Spray (CGS) Summer School took place in the nice Finca Pedro Pons in Barcelona in Spain from 12 to 13 June 2017. The lecturers from England, France Germany, Italy, Japan, Finland and Spain under the management of Prof. J. M. Guilemany and Dr. I. Cano covered entirely the field of CGS method, starting from the process feedstock up to its economics. The members of the European laboratories working in the area, including those from Helmut Schmidt University in Germany, The University of Barcelona in Spain, Tampere University of Technology in Finland, The University of Limoges in France, The University of Modena in Italy and Brunel University in London in England as well as the companies Air Product, Impact from Germany, Dycomat from The Netherlands and Plasma Giken from Japan presented their views on CGS technology in present and the perspectives of its development.

The first day presentations included the fundamentals of thermal spraying and the place of cold spray deposition in this field and were presented by Profs. Fauchais, Guilemany and Klassen followed by the introduction the cold spray technology made by Drs Cinca, Villa and Dosta. An interesting talk about gazes in cold spray technology was given by Dipl. Ing. Plicht. Finally, Profs Assadi and Klassen introduced their physical approach of optimizing the deposition process parameters using one variable η. Finally, a simplified model of deposition efficiency was introduced by Dr. Canales.

The second day presentations started with talk of Prof. Pawłowski and Dr. Bolleli about characterization of cold spray coatings properties and the methods used. The talks of Drs Villa, Dosta and Sanchez were about coatings applications from technical and economical points of view. Then the participants moved to the laboratory to listen for the practical talks about cold gas spray equipment given by Mr. Rozema, Prof. Vuoristo, Dipl. Ing Richter and Dr. Fukanuma. The school finished by an afternoon - workshop related to demonstration of the Thermal Spray Center Laboratory and the methods used at spray parameters optimization given by Drs Dosta and Canales. These talks initiated an animated discussion between the colleagues using physical and statistical approaches to reach the desired coatings properties.

Most of first and second day talks are shown in the section topics of the website (http://etsa-thermal-spray.org/members/topics)

The summer school attracted 14 participants from Czech Republic, France, Italy, Russia, Spain and the Netherlands.

The Summer School was finished on Wednesday morning by a meeting of the ETSA committee of directors. The discussion was concentrated on organization’s topics, future events (in Tampere and in Limoges in 2017 and in Plzen in 2018) and the preparation to the assembly general of ETSA which will take took place at RIPT meeting in Limoges on 6 – 8 December 2017.

Why become member ?

The website of the European Thermal Spray Association provides the useful information to all colleagues interested in thermal spraying in the large societies, job shops, or university laboratories. The ETSA members have access to the additional services such as job proposition, information about services related to thermal spraying in different European countries, forum of users which enbles research of missing information related to thermal spraying and much more.

The ETSA membership enables also a reduction in the fees of the events organized by the association.

We invite you to join ETSA!
